Lightning Event Counters
The Lightning Event Counter (LEC IV) is
a device for registering and recording
the number of strikes that the ERITECH
®
SYSTEM 3000 has intercepted. The design
of this counter allows many installation
alternatives on the downconductor
as discussed in later text. Also, see
Specifications on page 60.
The following should be considered prior to
installation of the Lightning Event Counter:
t
It is advisable to locate the LEC IV in
a secure area that is not prone to
contact with moving objects, theft,
or vandalism.
t
If the LEC IV is to be encased in an
additional enclosure, ensure that it is
mounted to enable easy access to the
display, (see figure 32 on page 48).
ERITECH ® DYNASPHERE
Terminals
The ERITECH ® DYNASPHERE is the air
terminal of the ERITECH SYSTEM 3000.
Ensure that the appropriate air terminal has
been provided.
Suitable for use in:
t
General purpose applications
t
High temperature environments
t
Corrosive environments (salt or acid
atmosphere)
Re-check:
t
Securing of downconductor - saddles,
cable ties, beam clamps, cable hangers,
etc, are appropriate.
t
Method of cable installation, ie. cable
upper terminated on the outside of the
drum - to be rolled off from the base of
the structure, or cable upper terminated
on the inside of the drum - to be rolled
off from the top of the structure,
(refer Figure 6 on page 15).
t
The outer sheath of the downconductor
must be electrically bonded to a
conductive structural point within 5 m
(17 ft) of the upper termination kit.
Structural Bonding Braid & Conductive
Structural Points
When installing the upper end of
the downconductor on a masonry
structure (concrete panels, brick,
etc), the downconductor should be secured
directly to the structural steel work. In
addition, the bonding cable (supplied in the
termination kit) must be connected via
6 mm
2 (8 AWG) insulated copper cable to
the nearest conductive structural point. This
point should be where the downconductor
first comes into contact with the structure
and may be either structural steel work or
the reinforcing within concrete panels or
slabs.
It is recommended that this point be
determined prior to the installation to allow
for any site work or equipment that may be
required prior to the installation.
The 6 mm 2 (8 AWG) cable is not supplied
and the length of the cable will need
to be determined and obtained before
commencing the installation.
